Description

Method and device for transmitting information

Technical Field

The present application relates to the field of communications, and more particularly, to methods and apparatus for transmitting information.

Background

In a wireless communication system, duplexing may be divided into Time Division Duplexing (TDD) and Frequency Division Duplexing (FDD) according to a duplex mode. Because the distribution of the terminal devices in the communication network is not uniform, and the uplink and downlink traffic volumes of different terminal devices may also be different, the uplink and downlink traffic volumes of different network devices in the same time period may be different. In the existing TDD or FDD mode, different network devices use the same uplink and downlink transmission configuration in the same time period, and thus the actual demand of the traffic of each network device cannot be met efficiently. Therefore, a more flexible duplexing technique is introduced in the prior art, that is, uplink and downlink transmissions of each cell can be configured individually according to actual service requirements, and this duplexing technique is generally referred to as a flexible duplexing technique.

In the existing flexible duplex technology, the flexibility of information transmission between the network device and the terminal device still has certain limitations. How to improve the flexibility of information transmission becomes a technical problem to be solved urgently.

Common terminals include, for example: a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, such as a smart watch, a smart band, a pedometer, etc.

To facilitate understanding of the embodiments of the present application, first, concepts and technologies related to the embodiments of the present application will be briefly described.

First direction transmission (second direction transmission): in the embodiment of the present application, the first direction transmission and the second direction transmission refer to two kinds of transmissions having different directions. For example, the first direction transmission is uplink transmission, and the second direction transmission is downlink transmission. For another example, the first direction transmission is a downlink transmission, and the second direction transmission is an uplink transmission. The specific situations of the first direction transmission and the second direction transmission can be flexibly set according to needs, and the embodiment of the application is not limited herein.

Time unit: in the embodiment of the present application, a time unit refers to a period of time, and for example, the time unit may be one subframe (subframe), one slot (slot), one mini-slot (mini-slot), or one symbol. The time unit may also be a plurality of subframes, a plurality of slots, a plurality of minislots, or a plurality of symbols, etc. Further, the time unit may be a time unit for scheduling a transport block in the communication system. For example, the time unit may be a Transmission Time Interval (TTI).

Time cell group: the N time cells constitute a time cell group. The time cells have numbers in the time cell groups. For example, the time unit group may be a frame and the time unit may be a subframe. For another example, the time unit group may be a subframe, and the time unit may be a symbol. As another example, the time unit group may be a time slot and the time unit may be a symbol.

And (3) uplink and downlink configuration: in this embodiment, the uplink and downlink configuration may be used to indicate time units for uplink transmission and time units for downlink transmission in N (N > 1) time units (the N time units may be the time unit groups in the foregoing, that is, each time unit group includes N time units). That is, the uplink and downlink configuration may be used to indicate the purpose of the N time units. It should be understood that the use includes use for uplink transmission or use for downlink transmission. For example, assuming that the time unit is a subframe, the uplink and downlink configuration may be a TDD frame configuration in an LTE system. For another example, assuming that the time unit is a symbol, the uplink and downlink configuration may be used to indicate the usage of each symbol in one subframe.

Hybrid automatic repeat request (HARQ) transmissions, which may include downlink HARQ transmissions and uplink HARQ transmissions.

And downlink HARQ transmission:

the network device may indicate resources for the network device to send data downstream to the terminal device. The process of resource indication is generally referred to as "downlink scheduling grant", and data transmitted by the network device in downlink is referred to as "downlink data". The interval between the downlink scheduling grant and the downlink data is n (n is more than or equal to 0) time units. That is, the terminal device may receive the downlink scheduling grant and the downlink data (n = 0) on one time unit; or the terminal device may receive downlink data (n > 0) n time units for downlink transmission after receiving the downlink scheduling grant.

And uplink HARQ transmission:

the network device may indicate resources for the terminal device to transmit data uplink to the terminal device. This process of resource indication is generally referred to as "uplink scheduling grant", and data transmitted uplink by the terminal device is referred to as "uplink data". The interval between the uplink scheduling grant and the uplink data is m time units. That is, the terminal device transmits uplink data on m (m > 0) time units for uplink transmission after receiving the uplink scheduling grant.

Feedback information indicating whether data is correctly received is fed back k (k > 0) time units after data transmission regardless of uplink HARQ transmission or downlink HARQ transmission.

Wherein the feedback information includes an Acknowledgement (ACK) for indicating that the data is correctly received and a Negative Acknowledgement (NACK) for indicating that the data is not correctly received.

In existing systems, the n, m, and k values may have different but fixed values. Taking the k value as an example, the k value may have different values including: the k values may have different values under different uplink and downlink configurations, and the k values corresponding to different time units may be different. The values for k that would be fixed may include: the k value for a time unit is fixed based on each uplink and downlink configuration.

For example, assuming uplink and downlink configurations as TDD frame configurations in the LTE system, table 1 shows TDD frame configurations in the LTE system.

TABLE 1

For downlink feedback of uplink data, it is agreed that a subframe in which a Physical Hybrid ARQ Indicator Channel (PHICH) corresponding to each uplink subframe (subframe used for uplink transmission) configured in each TDD frame is located is a kth subframe after the uplink subframe. For convenience of explanation, k of downlink feedback of uplink data may be denoted as k ₁ Table 2 is k based on TDD frame configuration ₁ The value of (a).

TABLE 2

As shown in table 2, in TDD frame configuration 0, subframe 2 corresponds to k ₁ The value of 4, i.e. the uplink data transmitted in subframe 2, is fed back in subframe 6. K corresponding to subframe 3 ₁ The value is 7, that is, the uplink data transmitted in the subframe 3 is fed back in the subframe 0 of the next radio frame. K for

sub-frames

2 and 3 ₁ Different in value, but k of subframe 2 ₁ Value fixed to 4, k of subframe 3 ₁ The value was fixed to 7.

Uplink inversion for downlink dataIt is given that a downlink subframe (subframe used for downlink transmission) corresponding to a Physical Uplink Control CHannel (PUCCH) of each Uplink subframe configured in each TDD frame is the kth subframe before the Uplink subframe. For convenience of explanation, k of uplink feedback of downlink data may be denoted as k ₂ Table 3 is k based on TDD frame configuration ₂ The value of (a).

TABLE 3

As shown in table 3, in TDD frame configuration 0, subframe 2 corresponds to k ₂ The value is 6, that is, the uplink feedback sent in subframe 2 is feedback for the downlink data in subframe 6 in the previous radio frame. K corresponding to subframe 4 ₂ The value is 4, that is, the uplink feedback transmitted in subframe 4 is feedback for the downlink data in subframe 0. K for

subframes

2 and 4 ₂ Different in value, but k of subframe 2 ₂ The value is fixed to 6 and the k value for subframe 4 is fixed to 4.

In a New Radio (NR) system, a network device may flexibly set n, m, and k values, and indicate the n, m, and k values to a terminal device. For example, the network device may indicate the n, m, and k values to the terminal device by transmitting Downlink Control Information (DCI).

In the prior art, a network device notifies a terminal device of uplink and downlink configuration of a local cell. Under the uplink and downlink configuration, the network device and the terminal device respectively determine a resource for transmitting certain information, and transmit the information by using the resource. During this period, the network device and the terminal device transmit information strictly according to the uplink and downlink configuration, so that the information can be transmitted correctly.

By adopting the mode to transmit information, the information can be ensured to be transmitted correctly. However, in practical applications, an emergency often occurs in a network, and the network device and the terminal device transmit information strictly according to uplink and downlink transmission configuration of the cell, so that the flexibility of information transmission still has a great limitation.

Based on this, the embodiments of the present application provide a method and an apparatus for transmitting information, which can improve flexibility of transmitting information.

Fig. 1 is an application scenario applicable to the embodiment of the present application. As shown in fig. 1, the application scenario includes a network device 101, and the application scenario further includes a terminal device 102 located within a coverage area of the network device 101, where the terminal device 102 may be multiple.

In this embodiment, the network device 101 may dynamically change the uplink and downlink configuration between the network device 101 and the terminal device 102 according to the actual situation.

Hereinafter, the method of the embodiment of the present application will be described in detail with reference to fig. 2 to 6.

FIG. 2 is a schematic interaction diagram of an example of a method according to an embodiment of the present application. It should be understood that fig. 2 shows detailed steps or operations of the method 200, but these steps or operations are merely examples, and other operations may also be performed or only some of the operations of fig. 2 may be performed by embodiments of the present application. The network device and the terminal device in fig. 2 may correspond to the network device 101 and the terminal device 102 in the communication scenario described above, respectively.

As shown in fig. 2, the method 200 may include 210, 220, 230, and 240.

210. When the uplink and downlink configuration between the network equipment and the terminal equipment is a first uplink and downlink configuration, the network equipment determines a first resource for transmitting first information; accordingly, the terminal device determines a first resource for transmitting the first information.

It should be understood that the first information may be understood as some (or some) information to be transmitted between the network device and the terminal device, and the first information may be uplink information (i.e., information transmitted by the terminal device in an uplink direction) or downlink information (i.e., information transmitted by the network device in a downlink direction). The first information may include data or feedback information indicating whether the data is correctly received.

It should also be understood that the first resource or the second resource of the embodiments of the present application may be a time domain resource. For example, the first resource is a first time unit. The first resource and the second resource in the embodiment of the application may also be time frequency resources. For example, the first resource is a first time unit in the time domain and a first frequency domain resource in the frequency domain. The first resource may also be other types of resources for transmitting the first information. For convenience of description, the first resource may be a first time unit or a time domain resource of the first resource may be a first time unit, and is denoted as "the first resource corresponds to the first time unit". Similarly, the following second resource corresponding to the second time unit can be understood as: the second resource is a second time unit or a time domain resource of the second resource is a second time unit.

The terminal device may determine the first resource in various ways.

For example, assuming that the first information is feedback information, as can be seen from the above, the network device and the terminal device may agree on the k value in advance. The network device may also indicate the k value to the terminal device through the DCI. The terminal device may determine the first resource based on the value of k.

For another example, assuming that the first information is data, the network device may indicate the first resource to the terminal device by transmitting scheduling information.

That is, the method 200 may further include:

201. the network equipment sends first scheduling information of first information to the terminal equipment, wherein the first scheduling information is used for indicating the first resource; accordingly, the terminal device receives the first scheduling information.

It is to be appreciated that the first scheduling information can explicitly indicate the first resource. For example, assuming that the first resource corresponds to a first time unit, the first scheduling information may directly indicate an index number of the first time unit. The first scheduling information may also implicitly indicate the first resource. For example, assuming that the first resource corresponds to a first time unit, the first scheduling information may also indicate the n, m, or k value above. The terminal device may determine the first time unit based on the n, m, or k value.

220. After the network equipment determines that the uplink and downlink configuration between the network equipment and the terminal equipment is a second uplink and downlink configuration, the network equipment sends indication information; correspondingly, the terminal equipment receives indication information from the network equipment, wherein the indication information is used for indicating the second uplink and downlink configuration.

It should be understood that, if the first information is downlink information, the network device and the terminal device perform transmission of the first information by: the network device sends the first information to the terminal device, and accordingly the terminal device receives the first information from the network device. If the first information is uplink information, the network device and the terminal device performing transmission of the first information means: the terminal device sends the first information to the network device, and accordingly the network device receives the first information from the terminal device.

Specifically, after the network device determines the first resource, or after the network device sends the first scheduling information, before the network device and the terminal device perform transmission of the first information, the network device may dynamically adjust uplink and downlink configurations, and send the indication information to the terminal device (i.e., send an adjustment result of the uplink and downlink configurations). After receiving the indication information, the terminal device may know that the uplink and downlink configuration is changed from the first uplink and downlink configuration to the second uplink and downlink configuration.

Optionally, the network device may configure the second uplink and downlink configuration semi-statically, or may configure the second uplink and downlink configuration dynamically. The condition for triggering the network device to change the uplink and downlink configuration may include a change period or a service to be transmitted. For example, the network device periodically changes the uplink and downlink configuration. As another example, the network device may change the uplink and downlink configuration based on a service, such as a low-latency and low-latency communications (URLLC) service.

230. The network equipment determines a second resource for transmitting the first information; correspondingly, the terminal equipment determines a second resource for transmitting the first information according to the indication information.

The usage of the time cell may change due to the change of the uplink and downlink configuration from the first uplink and downlink configuration to the second uplink and downlink configuration. If the terminal device and the network device also perform transmission of the first information according to the first resource, the first information may not be correctly transmitted.

Fig. 3 is a schematic diagram showing an example in which the first information cannot be correctly transmitted. The first information is assumed to be uplink feedback information of the first downlink data. As shown in fig. 3, in the first uplink and downlink configuration, according to the values of n and k (where the relevant description of n and k can refer to the above relevant description), time unit 3 (it should be understood that time unit x is a time unit numbered x) of time unit group (Z + 1) is used to transmit uplink feedback information of the first downlink data, that is, the first resource corresponds to time unit 3. Before the network device and the terminal device perform transmission of the uplink feedback information of the first downlink data, the uplink and downlink configuration is changed from the first uplink and downlink configuration to the second uplink and downlink configuration, and if the network device and the terminal device still transmit the uplink feedback information of the first downlink data on the first resource (time unit 3), transmission of the uplink feedback information may fail.

Fig. 4 is a schematic diagram of another example in which the first information cannot be correctly transmitted. The first information is assumed to be downlink feedback information of the first uplink data. As shown in fig. 4, in the first uplink and downlink configuration, according to the values of m and k (where the relevant description of m and k may refer to the above relevant description), the time unit 7 of the time unit group (Z + 1) is used to transmit the downlink feedback information of the first uplink data. I.e. the first resource corresponds to time unit 7. Before the network device and the terminal device perform transmission of the downlink feedback information of the first uplink data, the uplink and downlink configuration is changed from the first uplink and downlink configuration to the second uplink and downlink configuration, and if the network device and the terminal device still transmit the downlink feedback information of the first uplink data on the first resource (time unit 7), transmission of the downlink feedback information may be failed.

Fig. 5 is a schematic diagram of another example in which the first information cannot be correctly transmitted. The first information is assumed to be second downlink data. As shown in fig. 5, in the first uplink and downlink configuration, according to the value of n, time unit 2 of time unit group (Z + 1) is used for transmitting the second downlink data, that is, the first resource corresponds to time unit 2. Before the network device and the terminal device perform transmission of the second downlink data, the uplink and downlink configuration is changed from the first uplink and downlink configuration to the second uplink and downlink configuration, and if the network device and the terminal device still perform transmission of the second downlink data on the first resource (time unit 2), transmission failure of the second downlink data may be caused.

Fig. 6 is a schematic diagram of still another example in which the first information cannot be correctly transmitted. It is assumed that the first information is second uplink data. As shown in fig. 7, in the first uplink and downlink configuration, time unit 3 of time unit group (Z + 1) is used for transmitting the second uplink data according to the value m. I.e. the first resource corresponds to time unit 3. Before the network device and the terminal device perform transmission of the second uplink data, the uplink and downlink configuration is changed from the first uplink and downlink configuration to the second uplink and downlink configuration, and if the network device and the terminal device still perform transmission of the second uplink data on the first resource (time unit 3), transmission of the second uplink data may be failed.

Based on the above, if the uplink and downlink configuration changes after the terminal device determines the first resource for transmitting the first information and before the network device and the terminal device perform transmission of the first information, if the terminal device still uses the predetermined first resource to perform transmission of the first information, transmission failure of the first information may be caused. Therefore, the terminal device needs to determine the second resource for transmitting the first information. That is, the terminal device needs to determine the resource for transmitting the first information again.

Similarly, if the uplink and downlink configuration changes, the network device needs to determine the resource for transmitting the first information again.

It should be understood that the indication information of the embodiment of the present application may be used as trigger information for triggering the terminal device to determine the second resource of the first information. That is, if the terminal device does not receive the indication information, the terminal device may use the first resource to transmit the first information with the network device.

Taking a terminal device as an example (it should be understood that, without being contradicted, the following manners and the related description of the case and the like are also applicable to the network device), specifically, the 230 may include at least the following two manners:

mode 1

When the uplink and downlink configuration changes (from the first uplink and downlink configuration to the second uplink and downlink configuration), the terminal device needs to determine whether the usage of the first resource changes, and determine the second resource according to the determination result. For example, in the first uplink and downlink configuration, the first resource is used for transmission in the first direction, and the terminal device needs to determine whether the first resource is changed from being used for transmission in the first direction to being used for transmission in the second direction in the second uplink and downlink configuration.

Two cases may occur based on mode 1:

case 1

If the first resource is still used for transmission in the first direction, that is, the change of the uplink and downlink configuration does not affect the use of the first resource, the terminal device may continue to use the first resource to transmit the first information. That is, the terminal device determines the second resource as the first resource.

Still taking fig. 3 as an example, assuming that the first resource corresponds to time unit 4 in time unit group (Z + 1), since time unit 4 is still used for uplink transmission after the change, the network device and the terminal device may still use the first resource to perform transmission of the first information.

Case 2

If the first resource is changed from being used for transmission in the first direction to being used for transmission in the second direction. That is, the uplink and downlink configuration changes to affect the usage of the first resource, and the terminal device determines the second resource, which belongs to the resource used for the transmission in the first direction in the second uplink and downlink configuration.

Still taking fig. 3 as an example, it can be seen from the values of n and k that the first resource corresponds to time unit 3 in time unit group (Z + 1), and since time unit 3 is changed from being used for uplink transmission to being used for downlink transmission, the terminal device determines a certain time unit used for uplink transmission as the second resource.

Based on the case 2, the manner of determining the second resource by the terminal device may include at least one of the following two ways:

1. the second resource is determined based on a preset rule.

As an alternative example, the network device and the terminal device may make a predetermined appointment, assuming that the first resource corresponds to a first time unit, and a first available time unit after the first time unit is a time unit corresponding to the second resource.

For example, assuming that the first resource is a first time unit, the terminal device determines that the second resource is a first time unit used for transmission in the first direction after the first time unit in the second uplink and downlink configuration after the first time unit.

As an alternative example, it is assumed that the first information is uplink feedback information of downlink data, and the first scheduling information indicates that the first information is transmitted on a time unit (x + n + k), where x is an index of the time unit where the first scheduling information is received, and n and k may refer to the above related description.

Taking fig. 3 as an example, the first resource corresponds to time unit 3, and if the terminal device receives the indication information, the terminal device may determine that the second resource corresponds to time unit 4.

As another example, assuming that the first information is downlink feedback information of uplink data, and the first scheduling information indicates that the first information is transmitted on a time unit (x + m + k), where x, m, and k may refer to the above related description, since the usage of the time unit (x + m + k) changes, the terminal device may transmit the first information on a time unit for downlink transmission first after the time unit (x + m + k).

Taking fig. 4 as an example, the first resource corresponds to time unit 7, and if the terminal device receives the indication information, the terminal device determines time unit 0 of the second resource corresponding to time unit group (Z + 2). It is to be understood that time cell set (Z + 2) is the first time cell set after time cell set (Z + 1).

If the first information is feedback information, the second resource is determined based on the preset rule because the bit number occupied by the feedback information is small, and the influence of the first information on the information transmitted by the second time unit is favorably reduced.

2. The second resource is determined based on second scheduling information of the first information.

That is, while the terminal device receives the indication information from the network device, or after the terminal device receives the indication information from the network device, the method further includes:

202. the network equipment sends second scheduling information of the first information to the terminal equipment; correspondingly, the terminal device receives second scheduling information of the first information from the network device, wherein the second scheduling information is used for indicating the second resource.

It should be understood that the second scheduling information and the indication information may be carried in different time units, or may be carried in the same time unit.

It should also be understood that the second scheduling information may explicitly or implicitly indicate the second resource, and the specific description may refer to the above description related to the first information, which is not described herein for brevity.

The 230 may specifically include:

and the terminal equipment determines the second resource according to the indication information and the second scheduling information.

If the purposes of the plurality of time units are changed, the preset information passing through the plurality of time units is transmitted through the first available time unit, so that the preset information passing through the plurality of time units is easily transmitted on the same time unit, and the transmission of the information is collided. Based on this, the network device may determine that information for a time unit of the plurality of time units is transmitted over the first available time unit.

That is, the network device and the terminal device may agree in advance, and if the scheduling information sent by the network device is used to indicate a time unit with a changed usage, information indicating the time unit with the changed usage needs to be transmitted preferentially.

For example, the first information is information with a higher priority, the first resource used for transmitting the first information corresponds to a first time unit, and the second scheduling information may indicate that the second time unit corresponding to the second resource is a first available time unit after the first time unit in the second uplink and downlink configuration by indicating the first time unit.

In other words, the second scheduling information of the first information sent by the network device may be used to indicate the first time unit, and the terminal device determines, by receiving the second scheduling information, that the information carried in the first time unit needs to be preferentially transmitted, that is, the terminal device determines, by receiving the second scheduling information, that the second resource is the first available time unit after the first time unit.

Optionally, the network device and the terminal device may also agree that, if the scheduling information indicates a time unit with a changed usage, it is preset that information transmitted by a first available time unit after the time unit with the changed usage needs to be rescheduled.

Mode 2

When the uplink and downlink configuration changes, no matter whether the purpose of the first resource changes, the network device reallocates the resource for the first information, that is, the network device sends the second scheduling information of the first information, and accordingly, the terminal device receives the second scheduling information.

In this case, the first resource and the second resource may be the same or different. The network device may determine the second resource based on the actual situation. If the first resource and the second resource are time-frequency resources, the first resource and the second resource may be different from each other by: the time domain resources of the first resources and the second resources are different and the frequency domain resources are the same, or the time domain resources of the first resources and the second resources are the same and the frequency domain resources are different, or the time domain resources of the first resources and the second resources are different and the frequency domain resources are different.

240. The terminal equipment transmits the first information with the network equipment on the second resource; correspondingly, the network device transmits the first information with the terminal device on the second resource.

In the embodiment of the present application, when the network device has determined the first resource for transmitting the first information, the network device may still dynamically adjust the uplink and downlink configuration according to the actual situation, so that the flexibility of the network device and the terminal device in transmitting information can be improved. Further, in the case that the uplink and downlink configuration is changed, the terminal device re-determines the second resource for transmitting the first information, so that the first information is correctly transmitted. That is to say, the method of the embodiment of the present application can improve the flexibility of information transmission, and simultaneously enable the information to be correctly transmitted, and the method has better flexibility and applicability.

Optionally, when the first information is transmitted, the terminal device needs to know not only the second resource but also a transmission parameter for transmitting the first information. The transmission parameter may include at least one of parameters other than the second resource among parameters for transmitting the first information.

For example, assuming that the second resource is the second time unit, the transmission parameters may include parameters such as a frequency domain index and a modulation and coding mode.

For another example, assuming that the second resource is a time-frequency resource, the transmission parameters may include parameters such as adjusting a coding mode.

That is, the 240 may include:

and the terminal equipment transmits the first information with the network equipment on the second resource according to the transmission parameters.

Wherein the transmission parameter may include one of the following two types:

1) The transmission parameter is a preset parameter used for the network device and the terminal device to transmit the first information on the first resource. In other words, the transmission parameter is a parameter determined by the network device for the network device and the terminal device to perform transmission of the first information on the first resource. For convenience of explanation, such a transmission parameter may be referred to as a first transmission parameter. That is, before the first transmission parameter is changed from the uplink configuration to the downlink configuration, the network device configures the transmission parameter for the first information.

That is, the second scheduling information may include only a part of the parameters for scheduling the first information, and the terminal device may transmit the first information in combination with the first scheduling information and the second scheduling information. The method is advantageous for reducing the overhead of transmitting the first information. Alternatively, the terminal device may obtain the first transmission parameter by receiving the first scheduling information.

2) The transmission parameter is a parameter determined by the network device and used for the network device and the terminal device to transmit the first information on the second resource. For convenience of explanation, such a transmission parameter may be referred to as a second transmission parameter.

That is, the network device reconfigures the second transmission parameter for the first information under the second uplink and downlink configuration. Alternatively, the terminal device may obtain the second transmission parameter by receiving the second scheduling information. That is, the second scheduling information is also used to indicate the second transmission parameter. The second scheduling information may be complete information for scheduling the first information.

As can be seen from the foregoing, the first resource and the second resource may be time domain resources or time frequency resources. If the first resource is a first time unit, the second resource is a second time unit, and the first information is first feedback information used for indicating whether the first data is correctly received, as an optional example, the method 200 may further include:

the network equipment determines a second resource index according to the first resource index and the first index offset, wherein the second resource index meets the following formula:

n＝n,+n _offset ；

wherein n is a first resource index, the first resource index is an index of a resource in a third resource used for transmitting the first feedback information, a time domain resource of the third resource is the first time unit, n is the second resource index, the second resource index is an index of a resource in a fourth resource used for transmitting the first feedback information, the time domain resource of the fourth resource is the second time unit, n is _offset Is the first index offset.

As an optional example, the first resource index is specifically an index of a time-frequency resource used for transmitting the first feedback information in the third resource, and the second resource index is specifically an index of a time-frequency resource used for transmitting the first feedback information in the fourth resource.

As another example of the alternative, the first resource index is specifically an index of a frequency domain resource used for transmitting the first feedback information in the third resource, and the second resource index is specifically an index of a frequency domain resource used for transmitting the first feedback information in the fourth resource.

Optionally, the first directional transmission is downlink transmission, the first resource index is specifically a resource index of a PHICH resource used by the network device to send the first feedback information in the third resource, and the second resource index is specifically a resource index of a PHICH resource used by the network device to send the first feedback information in the fourth resource.

Optionally, the resource index of the PHICH resource may include a group index of the PHICH resource. The terminal device may determine the first resource index according to a method in an existing standard.

For example, the terminal device may determine the first resource index according to the following formula:

wherein the content of the first and second substances,

n is an index of a lowest physical resource block PRB among physical resource blocks PRBs of a physical uplink shared channel PUSCH for transmitting the first uplink data _DMRS For demodulation reference signal DMRS cyclic shift parameter, (. Mod (-) is a complementation function,

number of PHICH groups, I, included for the third resource _PHICH Is a value of 0 or 1,

is greater than 0 and the content of the active ingredient,

greater than 0. The parameters in the formula (1)Can be seen in the related specification of determining the group index of the PHICH resource in the existing standard (e.g., 3GPP standard).

As an alternative example, the second resource index may satisfy the formula based on formula (1):

wherein the content of the first and second substances,

is a first offset parameter, the first offset parameter is used to determine a first index offset, the first index offset

As another alternative, the second resource index may satisfy the formula based on formula (1):

wherein the first index offset

Optionally, the first directional transmission is uplink transmission, the first resource index is specifically a resource index of a PUCCH resource used by the terminal device to send the first feedback information in the third resource, and the second resource index is specifically a resource index of a PUCCH resource used by the terminal device to send the first feedback information in the fourth resource.

Alternatively, the terminal device may determine the first resource index according to a method in an existing standard.

wherein the content of the first and second substances,

configured to the terminal device by the network device through high-level signaling, n _CCE Is in sub-frame n-k _m The index of the first control channel element CCE used to transmit the corresponding downlink control channel PDCCH,

configured by the network device, N _p Is the total number of CCEs of p symbols in the PDCCH, N _p+1 Is the total number of CCEs of p +1 symbols within the PDCCH. The detailed description of each parameter in the formula (1) can be referred to the related description of determining the resource index of the PDCCH resource in the existing standard (e.g., 3GPP standard).

As an alternative example, the second resource index may satisfy the formula based on formula (4):

wherein the content of the first and second substances,

As another alternative, the second resource index may satisfy the formula based on formula (4):

wherein the first index offset

Specifically, if the network device directly sends the first information on the fourth resource according to the first resource index, a collision may occur between the transmission of the first information and the transmission of the second information. Wherein the second information refers to feedback information transmitted through a fourth resource before the first time unit is changed from being used for the first direction transmission to being used for the second direction transmission.

Based on this, there is a first index offset between the first resource index and the second resource index. The value of the first index offset may be greater than or equal to 0.

For example, assume that the fourth resource is not used for transmitting feedback information before the first time unit is changed from being used for transmission in the first direction to being used for transmission in the second direction. The first index offset may be equal to 0.

For another example, it is assumed that the fourth resource is also used for transmitting the second information before the first time unit is changed from being used for the transmission in the first direction to being used for the transmission in the second direction, and the first index offset is greater than 0 so as to reduce the probability that the transmission of the first information and the transmission of the second information generate a collision.

Further, the first index offset may satisfy:

n _offset ≥n _total

wherein n is _total The fourth resource includes a size of a resource for transmitting feedback information (the feedback information refers to feedback information other than the first information) before the first time unit is changed from being used for the first direction transmission to being used for the second direction transmission.

The method is advantageous for reducing the probability that the transmission of the first information and the transmission of the second information will collide.

The terminal device may determine the first index offset in a number of ways.

As an optional example, the terminal device determines the first index offset according to the index of the second time unit, the second uplink and downlink configuration, and a mapping table, where the mapping table records a corresponding relationship between the index of the time unit, the uplink and downlink configuration, and the index offset; or the mapping table records the corresponding relation among the index of the time unit, the uplink and downlink configuration and the offset parameter, and the offset parameter is used for determining the index offset. Accordingly, the network device may determine the first index offset in the same manner.

Table 4 is an example of the mapping table. The time unit is a subframe, the uplink and downlink are configured to be TDD frame configuration, and the mapping table records the corresponding relation among the index of the subframe, the TDD frame configuration and the offset parameter.

TABLE 4

Assuming that the second uplink/downlink configuration is TDD frame configuration 0, the first information is downlink feedback information of the first uplink data, and when the first uplink/downlink configuration is performed, the subframe 7 is used for transmitting the first information. Before the network device and the terminal device perform transmission of the first information, the uplink and downlink configuration is changed from the first uplink and downlink configuration to the second uplink and downlink configuration (that is, the second uplink and downlink configuration is TDD frame configuration 0), and as can be seen from table 1, the offset parameter is 2. The terminal device may determine the first offset according to the offset parameter, and further determine the second resource index.

As another alternative, the terminal device may obtain the first index offset by receiving offset information from the network device, where the offset information is used to indicate the first index offset.

Specifically, the network device may determine a first index offset (based on the transmission condition), determine offset information according to the first index offset, and send the offset information, so that the terminal device may obtain the first index offset.

It should be understood that the offset information may explicitly or implicitly indicate the first index offset, and specific description may refer to the above related description, which is not described herein for brevity.

In this embodiment of the present application, when the uplink and downlink configuration changes, first information originally transmitted through a first resource needs to be transmitted through a second resource, and third information originally transmitted through a fifth resource also needs to be transmitted through the second resource, where a resource offset (a first resource offset) corresponding to the first information is different from a resource offset (a second resource offset) corresponding to the third information.

For example, the first index offset is n _offet(1) Second resource offset n _offet(2) A maximum resource index corresponding to a resource used for transmitting the first information may be used. That is, the network device may determine, based on the first index offset, a time-frequency resource for transmitting the first information, and the network device may determine, based on the time-frequency resource for transmitting the first information, an index offset corresponding to the third information.

It should be understood that the description relating to the above manner and situation, etc., also applies to the network device. On the premise of no contradiction, the specific operation of the network device in the embodiment of the present application may refer to the specific operation of the above terminal device. For example, the process of determining the second resource by the network device may refer to the process of determining the second resource by the terminal device above. For another example, the process of the network device determining the second resource index offset may refer to the process of the terminal device determining the second resource index offset above.

Optionally, the 240 may include:

the terminal equipment transmits the first information with the network equipment on the time-frequency resource corresponding to the second index offset; correspondingly, the network device transmits the first information with the terminal device on the time-frequency resource corresponding to the second index offset.
